If you’re reading this blog, you probably know a thing or two about cars. You love diagnosing a problem in the vehicle and getting under the bonnet to fix it. With the right tools and a little knowledge, DIY car repairs are not a big deal.

Most car engine systems are fairly straightforward when you know the basics. That means the small problems can be fixed at home. Everything from changing brake pads to replacing air filters are simple tricks for car owners.

However, there are some things that even the most confident shouldn’t risk. Some things are best left to the pros. Today we’ll look at the five big areas that are best left to the car garage. Attempting to fix them yourself will cause even more problems and could result in injury.

Body Work

Amending bodywork is a no-go simply due to the machinery necessary. Professional garages use sophisticated metal fabrication machinery to manipulate bodywork. Even something as simple as pushing out a dent requires a skilled and deft touch. Anyone who’s ever had bodywork done on their car knows how expensive it can be. There’s a reason for this. It takes a skilled, experienced hand and very specific tools.


The windshield is one of the most important safety features of your car, which is why it is essential to retain your windows and ensure they are in good condition at all times. Driving with a chipped or cracked windscreen can put you and your passengers in further risk of injury during a collision.

This should be repaired by an experienced professional with years of skills behind them. The team at Total Windshields in Sydney will work with you to come up with the best solution for your damaged windscreen, whether that is to repair or replace. Visit their website.

Air conditioning

Any good mechanic will always tell you to steer clear of the air conditioning. There are a lot of delicate movements involved here. There are plenty of specific air pressure components that require a skilled hand. There is serious risk of injury when dealing with pressure tanks. Air conditioning also uses many harmful substances to function. If these leak, you risk causing harm to yourself.


Although the engine itself is a straightforward mechanical system, the electrics are not. They are a highly complex circuit that only skilled experience can understand. Simply diagnosing the source of an electrical problem is difficult. You’ll often make things worse by trying to get behind the circuit. If you think there’s a problem, ask the mechanics to look at it during your car servicing. They have the experience and skills to detect and fix electrical problems.

Changing the clutch

This one isn’t particularly complex or injury prone. However, any home mechanic will tell you the same thing. You’ll do it once, but you’ll never do it again. The clutch is deeply embedded within the engine structure. It often requires removing the entire engine and other components. It’s not difficult, just endlessly time consuming.

Automatic Transmission

Automatic transmissions are notoriously more difficult than their traditional counterparts. The system is much more complicated due to the mechanics and processing involved. Even at garages, these are often outsourced to factory geniuses. Best avoided in your home garage!

We’re all for getting under the bonnet, fixing things and understanding your car better. We love to get dirty and oily and replace broken parts. However, there are some things we just won’t touch. We advise you to do the same. You’ll save yourself time, money and frustration if you just take it to the garage. Until next time!
